"Jill's weight does not bother me at all," says Jill's mother, Cay. "Not at all."

Jill and her mother keep a secret from Kirk—after he goes to bed, they eat doughnuts and ice cream. "We'll just eat tons of them and leave them in the car and wait till he goes to work the next day and pull them out and eat some more," Cay reveals.

"We have to hide everything," Jill explains, "so he doesn't make us feel bad."
